Highest temperature in Paris on June 28?

Platform comparison

Market context

Paris-Le Bourget will likely see a high near 35°C on 28 June 2026, as the historic heatwave that peaked at 40°C earlier in the week begins to ease with a milder, storm-prone weekend. The current crowd-implied probability of 0% for any temperature above 35°C is misleading, given that the week’s plateau of extreme heat from Monday to Thursday already established a baseline well above typical June highs, and the cooling trend starting Friday is gradual rather than abrupt[1].

Historical precedents from 2011 and 2020 show that even when heatwaves ease, peak temperatures often remain in the mid-30s for several days, especially after a spring that was France’s warmest ever recorded at 13.8°C average[2]. The 29.8°C national thermal indicator set during the recent peak confirms that regional averages were already extreme, making a sudden drop below 32°C unlikely despite the forecasted thunderstorms[3].

Traders should monitor Wunderground’s real-time updates for Paris-Le Bourget on 28 June, particularly the timing and intensity of the expected thunderstorm showers, which could temporarily suppress the daily high but rarely prevent a mid-30s peak after such a hot week[1]. Météo France’s red alert status for 54 departments indicates persistent heat risk, and any delay in the cooling trend—still unconfirmed as of Friday—would keep temperatures near 35°C or higher[3]. Recent news from Sortiraparis confirms the weekend’s milder note but warns of storm risks that may not fully offset the accumulated heat[1].

What's the difference between match odds and outright odds?

Match odds cover a single game ("Bayern beats BVB"). Outright odds are long-term aggregates ("Bayern wins the league"). Outright markets have deeper liquidity; match markets have faster resolution.

Can I import form data and lineups?

This page shows the live Polymarket quote as an implied probability. Form data and lineups must be researched separately via sports data providers (e.g. Soccerway, ESPN, FBref) — we surface the market probability, not the sport analysis.
